SHARPAC Team

Hydrogen-energy systems, actuators, control, production, storage, and electrical energy conversion

Context

The SHARPAC team is made up of about 80 professors, researchers, engineers and PhD students. It develops its scientific activity in the application fields of electric vehicles and renewable energies. It is also particularly involved in the CNRS UAR FCLAB, dedicated to hydrogen energy and fuel cell systems.

Research objectives and themes

The research work of the SHARPAC team is structured around five scientific axes:

› Durability, performance and integration of fuel cell systems (FCS) – Facilitators: Samir JEMEÏ, Elodie PAHON. The research work concerns the increase in the durability of fuel cell systems integrating the study of auxiliaries (cooling, compression, recirculation, power electronics, etc.). Accelerated stress testing (AST) is also considered, as is life cycle analysis of fuel cells.

› Durability, performance and integration of electrolysis systems (ELYZ) – Facilitators: Frédéric DUBAS, Zhongliang LI. The work carried out within the ELYZ axis aims to improve the performance and efficiency of water electrolysers for hydrogen production and to integrate them efficiently into energy systems. These activities are based on standard and accelerated experimental tests to characterize electrolysers and systems, multiphysics modelling at different scales of granularity, as well as diagnosis and prognosis to manage the health and useful life of these systems.

›Static and electromagnetic converters (CONV) – Facilitators: Arnaud GAILLARD, Frédéric GUSTIN. This axis aims to develop static converters mainly of the DC-DC type with the use of large gap (SiC – GaN) components. The integration of intelligent functions as well as the reconfiguration of systems are also covered. A second part of the axis focuses on the optimization and modeling of rotary/linear polyphase electric actuators for high-speed and high torque density applications. The targeted application concerns both the field of hydrogen energy and that of electric mobility.

›Storage for electricity and hydrogen systems (STOCK) – Facilitators: Daniela CHRENKO, Abdesslem DJERDIR. The STOCK axis focuses on innovative technologies dedicated to energy storage, in electrochemical or electrostatic form (batteries and supercapacitors) and in hydrogen form. The research work focuses on better understanding the efficiency, reliability and durability of these technologies through the analysis of their state of charge and health states (SOC, SOH) taking into account the real conditions of use in embedded and stationary microgrids.

› Control, energy management and sizing of electrical systems (SYS) – Facilitator: Salah LAGHROUCHE. This axis focuses on improving energy efficiency through innovative control, energy management and sizing strategies. It mainly targets microgrids, electric and hybrid vehicles, as well as micro-cogeneration systems. Methods include nonlinear control, artificial intelligence, and systems optimization. The approaches evaluated cover technical, economic, environmental and social aspects, ensuring a holistic view of modern energy management.
